Mineral lubricant reinforced with Molybdenum bisulphide to handle heavy loads and reduce transmission noise. All mechanical transmission, synchronised or not synchronised gearboxes, gearbox/differential, transfer gearbox and hypoid differentials without limited slip system operating under shocks, heavy loads and low revolution speed or moderate loads and high revolution speed. Very high lubricating power decreases friction and wear. SAE 90 grade at hot temperature to provide outstanding oil film resistan
